Make sure to power o the unit rst, then set the DIP Switches to the correct positions and then power on the transmitter. GENERAL INFORMATION The DLP Series is based on a piezoresistive, silicon sensing element which senses Dierential Pressure and provides an analog output. Field selectable analog outputs include 0-5 and 0-10 VDC, or 4-20 mA which correlate to a uni or bi-directional pressure range from 0-0.1” up to 0-40” of water column, depending on your model selection. Each unit has up to 8 eld selectable, uni or bi-directional ranges (see Figure 6 p. 3). MEDIA The DLP can be used to monitor the dierential pressure in any application that uses dry air or inert gas. Mounting Find a suitable location for the enclosure. The DLP has 2 two mounting holes located on the top and bottom anges. Drill pilot holes for the (2) #8 x 3/4” self-drilling screws(supplied). Use the enclosure ange as a guide, or use the dimensions listed in Figure 1 . Mount the unit vertically with the brass ttings pointing towards the ground. This ensures that any condensation that may form in the tubing does not have an eect on the pressure sensor. If mounting the unit horizontally, a slight zero shift may occur and care must be taken to prevent moisture from building up in the sensor.

To mount the sensor on the DIN Rail, place the bottom of the DIN Rail Clip into the 35mm DIN Rail and push the unit upward to engage the spring clip. Now press the top of the unit back until it locks into place - see FIGURE 2 (p.1). PITOT TUBE INSTALLATION (Optional) Slip the rubber washer over the threaded end of the pitot tube, keeping the washer as close to the threaded end as possible. Fasten the pitot into the threaded insert on the back of the enclosure. Press the rubber washer against the enclosure - see FIGURE 3 . Tubing Setup When Pitot Tube is Installed Units will be shipped with silicone tubing attached to the high and low pressure barb ttings. The silicone tubing will need to be removed from the High Pressure (H) barb tting and secured onto the pitot tube barb tting. This will leave the high pressure barb tting open to atmosphere, and the Low pressure barb tting remaining at default setup. Pressure Connections The recommended connection tubing is ¼” O.D push-on tubing (1/8” to 3/16” I.D.). For best results, all tubing lengths should be limited to a maximum length of 75 feet (23 meters). Longer runs will aect the response time.

Never connect or disconnect wiring with power applied. •When using a shielded cable, ground the shield only at the controller end. Grounding both ends can cause a ground loop. •It is recommended you use an isolated UL-listed class 2 transformer when powering the unit with 24 VAC. Failure to wire the devices with the correct polarity when sharing transformers may result in damage to any device powered by the shared transformer. •If the 24 VDC or 24VAC power is shared with devices that have coils such as relays, solenoids, or other inductors, each coil must have an MOV, DC/AC Transorb, Transient Voltage Suppressor (ACI Part: 142583), or diode placed across the coil or inductor. The cathode, or banded side of the DC Transorb or diode, connects to the positive side of the power supply. Without these snubbers, coils produce very large voltage spikes when de-energizing that can cause malfunction or destruction of electronic circuits.

ACI recommends 16 to 26 AWG twisted pair wires or shielded cable for all transmitters. Twisted pair may be used for 2-wire current output transmitters or 3-wire for voltage output. Connect the wires to the unit’s nger push-button terminal blocks. Each DLP unit can be congured to three output signals: 4-20 mA, 0-5 V or 0-10 V. Use the Wiring Connections and diagrams to determine the proper wiring for your application. See TABLE 1 (p.3) for Output Mode and Output Signal switch positions. Note: When using 1/2” conduit, the strain relief tting must be removed from the enclosure. Note: Make sure that any conduit or metal ttings do not come in contact with the circuit board. AUTO ZERO SW2 ZERO FUNCTION The DLP unit should be “ZEROED” before pressure is applied to the unit. The zero button is used to cancel out any osets caused by installation and sensor drift. The Zero adjustment must be performed with NO pressure applied to either side of the sensor. Remove the tubing connected to the H(High) and/or L(Low) pressure ttings. Push “ZERO” button for more than three seconds before installation or whenever necessary. For units with LCD display, “AUTOZERO” icon will be on when the unit enters zero mode. If zeroing process is successful, the “AUTOZERO” icon will ash twice. PRESSURE RANGE SELECTION If a custom calibrated pressure range is ordered, DO NOT change the Pressure Range Selection DIP switch settings. Table 2 lists ACI’s 12 standard model #’s.

Each unit could have up to eight eld selectable, uni or bidirectional ranges. CAUTION •See TABLE 3 for your DLP model’s maximum pressure. •DO NOT switch pressure range or output mode when POWER is ON. Make sure POWER to the unit is OFF. Failure to do so WILL NOT ALLOW any new switch settings to take place. •Choose dierential pressure range based on the expected dierential pressure in your application. Move switches to the correct positions and THEN POWER ON the transmitter.

Note: In Bidirectional mode, a value of 0 inWC will have an output equal to 50% of the output signal range (12mA, 2.5V, 5V). ADDITIONAL LCD FEATURES LCD Engineering Units Adjustment This option is ONLY for units with LCD display. Switch DIP switch SW3 position three to select Pa or inWC. If switched with power on, unit change will not take place until power is cycled. “Out Of Range” “OUT OF RANGE” icon will be on when dierential pressure is over or under the minimum or maximum pressure range selected. If a DLP unit is outputting “OUT OF RANGE”, please turn o the unit immediately, and check the pressure input with a gauge or other test instrument. Once the pressure has been veried, set the Pressure Range Selection DIP switch to the proper positions based upon your maximum expected dierential pressure. CALIBRATION DLP utilizes a digital pot for Span calibration and is factory set. There is no Span potentiometer for adjustment. In the event you require Span calibration, the unit must be sent back to ACI. The Oset can be adjusted using the Auto Zero function discussed on pg 4. Drift is a function of stress relaxation over time and this results in the oset shifting, and not the span . Periodically re-zeroing the device will eliminate the eect of drift.PRODUCT SPECIFICATIONS Automation Components, Inc. 2305 Pleasant View Road | Middleton, WI 53562 Phone: 1-888-967-5224 | Website: workaci.com Page 7 Version: 19.0 I0000777 4-20 mA Output: 16-36 VDC (250 Load max.) / 22-36 VDC (500 Load max.) 0-5 VDC / 0-10 VDC Output: 15-36 VDC into > 5K Ohm Load / 24 VAC (+/- 10%), 50/60 Hz 4-20 mA Output: 24 mA minimum | 0-5 VDC / 0-10 VDC Output: 6 mA maximum Current Output: 4-20 mA, 2-Wire (Standard); (Current limited to 21.4 mA max) Voltage Signals: 0-5 VDC / 0-10 VDC, 3-Wire; Output limited @ 5.25 & 10.5 VDC) 4 seconds 0.5 second +/- 0.5% FSO; +/- 0.25% (Only for Specied Range) Pushbutton Zero Function +/- 0.067% FSO / °F (0.12% FSO / °C) A/DLP-001: Proof: 270 inWC (67.2 kPa) | Burst: 415 inWC (103.3 kPa) for 1 inWC (249.8 Pa) A/DLP-010: Proof: 350 inWC (87.12 kPa) | Burst: 550 inWC (136.9 kPa) for 10 inWC (2490.8 Pa) A/DLP-040: Proof: 562 inWC (140 kPa) | Burst: 1004.7 inWC (250 kPa) for 40 inWC (9963.6 Pa) -4 to 185 °F (-20 to 85 °C) 32 to 122 °F (0 to 50 °C) -22 to 185 °F (-30 to 85 °C) 10 to 95% RH, non-condensing Dry air or inert non-conductive gases Flame Retardant Polycarbonate; UL94-5VA Finger Pushbutton (Spring) Terminal Blocks; accepts 16-24 AWG wires Watertight Cordgrip Installed (1/2" NPT Conduit ttings accepted when Cordgrip removed) Nickel Plated Brass or Stainless Steel SPECIFICATIONS Supply Voltage: Supply Current: Output Signals: Response Time (0-100% FSO): Output Update Rate: Accuracy¹: Zero Function: Thermal Eects²: Proof Pressure / Burst Pressure: Operating Temperature Range: Compensated Temperature Range: Storage Temperature Range: Operating Humidity Range: Media Types: Enclosure Material / Flammability Rating: Wiring Connections: Conduit Knockouts: Pressure Fitting Material: W.E.E.E.
